The commit 9a397f473657 ("ASoC: cs4271: add regulator consumer support")
has introduced regulators in the driver.
Regulators are enabled at the beginning of component_probe() but they
are not disabled on errors. This can lead to unbalanced enable/disable.
Fix the error path to disable regulators on errors.
